Multiple dose pharmacokinetics of cefpodoxime in young adult and elderly patients.
Multiple dose pharmacokinetics of a new third-generation cephalosporin, cefpodoxime, were evaluated in adults (15, 18-60 years) and elderly adults (10, greater than or equal to 70 years), all out-patients suffering from acute lower respiratory tract infection. A dose of 200 mg cefpodoxime proxetil (expressed in mg cefpodoxime) was administered 12-hourly for seven to ten days and timed blood samples were evaluated on days 0, 3, 5, 6/7 and on the last day of treatment. Results showed that the pharmacokinetics in adult and elderly patients were comparable with those of healthy volunteers and with each other, with the exception of one elderly patient with severe renal impairment. Dosage adjustment of cefpodoxime proxetil does not therefore appear to be necessary in the elderly unless there is evidence of severe renal insufficiency.
